Taking Apart the CX100

Step One

From the front of the speaker, remove the fabric covers.

From the reverse side, remove the backplate.

Remove the dampening material.

Cut all of the wires connecting the drivers to the back plate.

NOTE

Evaluate the state of the speaker drivers and make sure they are in good condition. If the speaker foams are damaged a repair is needed.

You can either:
a) refoam yourself

b) buy new drivers compatiable with the original

c) get them repaired by a professional

Creating a new power connection

Step two

Remove the original plastic speaker connector with a saw. Make sure to cut

through the wider end, upon which you will be later placing the 3D printed puck.

Screw the power plug into 3D printed puck.

Apply glue to the 3D printed holder. Make sure to cover all the inner walls with a sucient amount of glue and attach it to the hole on the back plate.

Strip the insulated wires you reserved for the power connector, so that approximately 1cm of wire is exposed.

Check the polarity of the power supply (which is +/-) and identify the corresponding pin on the power plug.
Solder both wires to the power plug pins.

Assemble the parts

Step three

Strip the wires coming from the drivers, so that again approximately 1 cm of wire is exposed.

Place the Raspberry Pi upon the BeoCreate 4-Channel Amplifier.

Install spacers to three corners of topside of the Pi using the supplied nuts as seen in the pictures (there are both nuts and screws in the box).

Screw the 4CA to the frame. Don’t use screws in the holes that will be covered by the spacers.

Install the Pi onto the 4CA. The spacers won’t a x the Pi to the 4CA, but just pre- vent it from flexing and touching any components on it.

Fit in the cut wires into the Amplifier.

Closing up

Step four

Connect the power supply.

Plug the power supply into a wall socket.

Make sure a red light turns on on the Raspberry Pi.

Unplug the power supply from the wall socket to further proceed with the

up-cycling.

Now prepare the SD card, by downloading its relevant software:

www.hifiberry.com/build/documentation/beocreate/ beocreate-how-to-start/

Insert the SD card into the Raspberry Pi.

Reinsert the dampening material and place the electronics on the top compartment of the speaker.

Screw on the back plate.

ENJOY

Your speaker is now physically upcycled.
